"Both libraries make it easy for developers write applications that will run on different platforms without having to rewrite a lot of code. GTK+ has had a huge impact on the way Wireshark looks and feels and on its popularity but it doesn’t cover our supported platforms as effectively as it should and the situation is getting worse as time goes on."
